The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In order to facilitate understanding of the scheme, a brief introduction is now made to the scenario and related words of the scheme. In the application, a block chain-based multi-party combined research and development system is pre-existing and is a platform, for convenience in description, the system of the block chain-based multi-party combined research and development system is called a management and control platform, the system can also bear some operations, the system is based on the block chain, the block chain is a distributed system, the trust problem of traditional centralized transaction is solved, the positions of participating parties are equal, and an anonymous transaction mode can be adopted; the organization generally refers to a organization group or a working unit, and in the application, the organization is divided into four categories, namely a project initiator, a project participant, a project transferor and a project receiver according to different functions when executing a specific project.
Before the organization actually implements the project, there are two application operations, see fig. 1, where fig. 1 is an exemplary diagram of a flow of two application operations performed by the organization before implementing the project, the first is a system for applying for adding to a block chain-based multi-party combined development system, i.e., applying for adding to a management and control platform, and the second is an application for adding to the project. The specific situation is as follows:
applying for adding a management and control platform: the mechanism applies for joining the management and control platform, a registration application for joining needs to be initiated to the management and control platform, the management and control platform has nodes to be commonly known, if the nodes are commonly known, the mechanism becomes a registration mechanism of the management and control platform, the registration mechanism is a mechanism for successfully joining the management and control platform, in the link, the mechanism is used as the mechanism and is not related to the execution of specific projects, so the mechanism is not classified according to functions at present, namely, the mechanism is unrelated to a project initiator, a project participant, a project transferor and a project receiver.
Applying for an added item: the mechanism that successfully joins the management and control platform, that is, the registration mechanism, may select a manner of executing the project according to actual requirements, that is, apply for joining a specific project, for example, may initiate the project or participate in the project, if it wants to initiate the project, it is a project initiator, if it wants to join a certain project, it is a project participant, and if it wants to join a certain project, it needs to initiate a request for applying for joining the project, and specific details are described below.

For example, an organization a wants to participate in a block chain-based multi-party joint development system, that is, wants to participate in a management and control platform, first needs to send a registration application to the management and control platform, where the registration application may include related information such as application information, application qualification, organization name, organization member, and organization qualification.
And the management and control platform is configured to broadcast the registration application to each block chain node of the management and control platform after receiving the registration application. Referring to fig. 2, fig. 2 is an exemplary diagram of a process of performing consensus on a registration application by a block link point, after receiving the registration application, a management and control platform broadcasts the registration application to each block link node of the management and control platform, as shown in the diagram, the management and control platform broadcasts the registration application to a node 1, a node 2, a node 3 to a node n, and n nodes participate in the consensus of the registration application, where the node belongs to an organization that the management and control platform has registered authentication, and if the node can be qualified for qualification authentication, role authentication, etc., the node qualified for participation in the consensus of the block link through registration authentication is qualified, and in addition, the node may be endowed with a specific function in advance, for example, an authentication function, a consensus function, etc., are endowed according to actual requirements.
And the block chain node is configured to perform consensus on the registration application and feed back the consensus result to the mechanism. With reference to fig. 2, after each node of the blockchain receives a registration application, an authentication function is started to perform consensus on the registration application, such as checking application information and application qualification, if all information is legal and compliant, the consensus is passed, and a check result is broadcasted to other nodes in the management and control platform, each node corresponds to one check result, such as node 1 corresponds to check result 1, node n corresponds to check result n, and n check results are broadcasted to other nodes in the blockchain. If the nodes in the block chain exceeding the preset ratio reach the consensus of the registration application, the registration application passes the consensus. For example, the predetermined ratio is 51%, that is, if more than 51% of nodes in the blockchain management platform agree with the registration application, the registration application passes the agreement, and the registration application passes the agreement.
And the management and control platform is further configured to allocate the identity for the organization if the registration application passes, and trigger the intelligent contract to call the key generator to generate and distribute the key for the identity.
